Its almost my b-day and i am needing some help. 1) If i buy a K&N air filter is it necessesary to buy the jet kit. 2) I am also looking into a Supertrap IDS2 muffler for my 97KingQuad. When i install it what mods will i have to make with the carb jetts and other things. I don't know much so any help will do. And another thing for you 4x4 ppl can you tell a significant power increase with these 2 mods. Thanx.
when these quads come from the factory they are set up to run a little on the rich side ( alittle )If/when you pipe them and modify the air box you let more air in and more air out so in order for them to run right you MUST rejet or you will run lean and burn them up
if you want more power then you will have ot go for the muffler , modify the air box and rejet , dont be afraid just go for it , when you take the bottom of the carb off you will see a jet ( its a little brass screw with a hole in the middle of it ) it will have a number stamped on it , take the number to your dealer and ask for the next size bigger , then just put it back together
